Synthetic peptide from internal sequence residues of Human AGRP (NM_001138.1).
Human fetal brain and fetal testis lysates.
This antibody gave a positive result when used in the following formaldehyde fixed cell lines: HeLa.
Lyophilised:Reconstitute with 200ul distilled H2O. Please note that if you receive this product in liquid form it has already been reconstituted as described and no further reconstitution is necessary.
Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid repeated freeze / thaw cycles.
Plays a role in weight homeostasis. Plays a role in the central control of feeding. Reduces food intake. Inhibits cAMP production mediated by stimulation of melanocortin receptors within the hypothalamus and adrenal gland. Acts primarily on MC3R and MC4R. Has very low activity with MC5R.
Expressed primarily in the adrenal gland, subthalamic nucleus, and hypothalamus, with a lower level of expression occurring in testis, lung, and kidney.
Genetic variations in AGRP may be a cause of obesity (OBESITY) [MIM:601665]. It is a condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat.
Contains 1 agouti domain.
The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin.
ICC/IF image of ab113481 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab113481 at 10µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 goat anti- rabbit (ab150081) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.
